Description
Vorrichtung zum passergerechten Anlegen von Bogen in Bogenrotationsdruckmas chinen Die Erfindung betrifft eine Vorrichtung zum passergerechten Anlegen von schuppenförmig mit einer Anzahl in Förderrichtung umlaufender Transportbänder zu den Vordermarken bewegten Bogen in Bogen tationsdruckmas chinene Bekanntlich werden die vom Anlegestapel einzeln abgehobenen Bogen in der sogenannten Anlage vor der Übernahme beispielsweise durch Schwinggreiferg welche die Bogen den Greifersystemen des Druckzylinders oder einer Anlegetrommel übergeben, nach der Vorderkante und nach der Seite hin ausgerichtet. Zu diesem Zweck sind Anlea, gemarken und Seitenziehmarken am Anlegetisch vorgesehen. Bei schnellaufenden Druckmaschinen, de h. rascher Bogenfolge, werZ den die Bogen dabei von einer bestimmten Formatlänge an geschuppt in der Anlage zugeführt, so daß der anzulegende Bogen bereits an die Vorderkante geführt und ausgerichtet wird1 während der vorher gehende> abziehende Bogen denselben noch überdeckt. Während des Ausrichtevorgangs der Vorderkante muß gleichzeitig auch das Ausrich ten des Bogens nach der Seite erfolgen. Die hierfür zur Verfügung stehende Zeit ist zwar normalerweise nur kurz (1/25 sec) sie darf aber auch bei hohen Maschinengeschwindigkeiten nicht unterschritten werden, um ein Rückprallen des Bogens von der Seitenmarke zu unwerbinden, Das hat jedoch zur Folge, daß bei überlappter Bogenzufuhr die Seitenziehmarke dem nachfolgenden Bogen im Wege ist und zu Betriebsstörungen Anlaß gibt. Device for registering sheets in sheet-fed rotary printing machines chinen The invention relates to a device for the registration of scales with a number of conveyor belts running in the direction of conveyance to the front lays moving sheets in sheet tationsdruckmas chinene known to be from the feed pile individually lifted sheets in the so-called system before the takeover, for example by Schwinggreiferg which the sheets to the gripper systems of the printing cylinder or transferred to a feed drum, aligned to the front edge and to the side. Anlea, marked and side pull marks are provided on the feed table for this purpose. With high-speed printing machines, de h. rapid succession of arcs, the arcs will be in this case, from a certain format length, fed to the system in flaked form, so that the sheet to be placed is already guided to the leading edge and aligned1 while the previous> peeling arc still covers it. While the alignment process of the front edge must also be the alignment th of the arch to the side. The time available for this is normally only briefly (1/25 sec) but it can also be used at high machine speeds must not be undershot in order to prevent the sheet from rebounding from the side mark unbinding, however, this has the consequence that if the sheet feed is overlapped, the side pull tab is in the way of the following arc and gives rise to operational disruptions.
Aufgabe der Erfindung ist es, ein passerhaltiges Anlegen des Bogens an die Seitenmarke bei schuppenförmiger Bogenzufuhr und höchsten Maschinengeschwindigkeiten mit sehr geringem Aufwand zu gewährleisten, Nach der Erfindung wird dies dadurch erreicht, daß die Transportbänder mit ihren Umlenkrollen in der Förderebene schwenkbar angeordnet sind. Durch diese Maßnahme ist es in einfachster Weise mögw lich, die ankommenden Bogen exakt an die Seitenmarke heranzuführen, wobei gleichzeitig durch Entlangstreifen der vorderen Ecke des Bogens an der Seitenmarke selbsttätig ein Ausrichten der Bogenvorderkante erfolgt. Die Bogenführung ist dabei zudem zu keinem Zeitpunkt unterbrochen und eine Beeinträchtigung durch über dem Anleger tisch befindliche bewegte,fürfürdie Seitenanlage erforderliche Teile vermieten.The object of the invention is to create a register with the sheet to the side mark with scaled sheet feed and highest machine speeds to ensure with very little effort, According to the invention this is achieved that the conveyor belts can be pivoted with their pulleys in the conveying plane are arranged. By this measure, it is possible in the simplest way, please include the to bring incoming sheets exactly to the side mark, while at the same time Automatically strip along the front corner of the sheet at the side mark Alignment of the leading edge of the sheet takes place. The bow guidance is also not to any Time interrupted and an impairment by the table above the feeder Rent moving parts required for the side system.
Weitere Merkmale der Erfindung ergeben sich aus den Unteransprü chen. In der Beschreibung ist ein Ausführungsbeispiel der Erfindung anhand der Zeichnung erläutert.Further features of the invention emerge from the subclaims. In the description, an embodiment of the invention is based on the drawing explained.
Es zeigen Figur 1 ein Druckwerk einer Bogenrotations druckmaschine mit Anlegetisch und Anlegestapel, Figur 2 eine Draufsicht auf die Druckmaschine nach Figur 1.FIG. 1 shows a printing unit of a sheet-fed rotary printing machine with feed table and feed stack, Figure 2 is a plan view of the printing machine according to Figure 1.
In der Figur 1 ist mit 1 schematisch das erste Druckwerk einer Bo genrotationsOffsetdruckmaschine mit in Reihe angeordneten Druckwerken bezeichnet. Dieses besteht in bekannter Weise aus einem Plattenzylinder 2, einem Gummizylinder 3 und einem Druckzylinder 4, dem die zu bedruckenden Bogen schuppenförmig von einem Stapel 5 über einen mit Transportbändern 6 versehenen Anlegetisch 7 und eine Anlegetrommel 8 zugeführt werden. Nach dem Druckvorgang zwischen dem Gummizylinder 3 und dem Druckzylinder 4 wird der Bogen zwecks Auftragen einer weiteren Farbe über eine oder mehrere Überführtrommeln 9 dem nächsten Druckwerk zugeführt.In the figure 1 is with 1 schematically the first printing unit of a Bo Genrotation offset printing machine with printing units arranged in a row. This consists in a known manner of a plate cylinder 2, a rubber cylinder 3 and a printing cylinder 4, to which the sheets to be printed are flaked by a Stack 5 over a feed table 7 provided with conveyor belts 6 and a feed drum 8 are fed. After the printing process between the blanket cylinder 3 and the impression cylinder 4 the sheet is fed over one or more transfer drums for the purpose of applying another color 9 fed to the next printing unit.
Vor der Übernahme des Bogens durch die Greifer der Anlegetrommel 8 muß dieser an der Vorderkante geradegerichtet unter die Vordermarken 10 einlaufen und an einer Seitenmarke 11 ausgerichtet werden.Before the sheet is taken over by the gripper of the feed drum 8 this must run straight under the front lays 10 at the front edge and aligned with a side mark 11.
Mit 12 sind sogenannte Schwinggreifer bezeichnet, die den zu bedruk kenden Bogen vom dem Anlegetisch vorgelagerten Anlegeblech 13 der Anlegetrommel 8 zuführens Um eine passergerechte Anlage zu gewährleisten, sind die Transportbänder 6 mit ihren Umlenkrollen 14, 15 in der Förderebene des Anlegetisches 7 schwenkbar gelagerte Durch diese Maßnahme werden die Bogen 16 zwar schräg an die Seitenmarke 11 am Anlegeblech 13 herangeführt, während des Transports desselben längs der Seitenmarke aber etwas geschwenkt, so daß die Vorderkante 16 richtig, dç h0 parallel unter die Vordermarken gelangt und die Seitenkante des Bogens jeweils an einer der Seitenmarken 11 anliegt, Um dies zu bewerkstelligen sind die Transportbänder 6 mit den Umlenkrollen 14, 15 auf einem um eine gemeinsame Achse 17 am Anlegetisch 7 schwenk baren Gestell 18 gelagert. Durch einfaches entsprechendes Verschwenken des Gestells 18 kann jeder vom Stapel 5 herrührenden seitlichen Abweichung der Bogenseitenkante schnell nachgekommen und die Bogen können passergerecht angelegt werden0With 12 so-called oscillating grippers are referred to, which are too bedruk Kenden sheet from the feed table upstream of the feed plate 13 of the feed drum 8 feeding To ensure that the system is correctly registered, the conveyor belts 6 with their pulleys 14, 15 in the conveying plane of the feed table 7th pivotably mounted By this measure, the sheets 16 are indeed obliquely to the Side mark 11 brought up on the contact plate 13, during the transport of the same but pivoted a little along the side mark so that the front edge 16 is correct, dç h0 comes parallel under the front lays and the side edge of the sheet in each case against one of the side marks 11, the conveyor belts are used to accomplish this 6 with the pulleys 14, 15 on a common axis 17 on the feed table 7 pivotable frame 18 mounted. By simply swiveling accordingly of the frame 18 can be any lateral deviation of the sheet side edge resulting from the stack 5 quickly followed and the sheets can be created in register0
